The US2 includes a necklace-style set of earphones (with 2 connections to the device) so that you can’t easily lose it. The connections are very strong – so strong that I had a bit of difficulty removing the connector so I could plug the charge/USB connection into the device! You can use the necklace earphones or use the two audio ports to connect 2two different sets of earphones for sharing. Also in the package are a slipcase, a USB/power adapter (no external AC power is included) some screen protectors, instructions, and software for managing lyrics and for converting video into the MSV media clip format.
